3.2.1
DIMM Configuration Rules
Sun Ultra 45 or Ultra 25 workstation memory is installed as matched pairs of DDR-1
SDRAM 266-MHz DIMMs. Within a matched pair, DIMMs must be identical. They
must be from the same manufacturer with the same type and number of memory
devices, the same amount of memory per device, and the same memory speed.
■
The Sun Ultra 45 or Ultra 25 workstation requires a minimum of two matching
DIMMs installed in CPU0 (FIGURE 3-3).
■
DIMM connectors on the motherboard are color-coded blue and black. Beginning
with CPU0, install DIMMS in pairs, either in the blue or in the black connectors.
■
If you have four DIMMS and two CPUs, install two DIMMs for CPU0 and two for
CPU1 for optimum performance (FIGURE 3-4).
When the workstation boots, the OpenBoot PROM checks for compatible memory
modules. See “OpenBoot PROM Memory Message” on page 3-6 for additional
information.
Before replacing Sun Ultra 45 and Ultra 25 memory, verify that the latest versions of
OpenBoot PROM, system firmware, and recommended system patches are installed
on your system. If necessary, check the Sun System Handbook at SunSolve Online:
http://sunsolve.sun.com/handbook_pub/
FIGURE 3-3
DIMM Configurations for Single-CPU Workstations

OpenBoot PROM Memory Message
During workstation startup, OpenBoot PROM checks for DIMM type and DIMM
manufacturer. TABLE 3-1 shows some checks and the actions taken by the OpenBoot
PROM.
TABLE 3-1
OpenBoot PROM Memory Checks and Actions
Check
Message
Action Taken by System
Wrong DIMM type
NOTICE - CPUx Banky DIMMs
are incorrect type.
A message is displayed and the
workstation powers off.
DIMMs in a pair have
different architecture
NOTICE - CPUx Banky DIMMs
have different
architectures and will not
be used.
Workstation does not use dissimilar
DIMMs. A message is displayed and the
workstation continues to boot; the
workstation attempts to use the DIMM
pair.
DIMMs in a pair are from
different manufacturers
NOTICE - CPUx Banky DIMMs
are from different
vendors.
Workstation uses DIMMs from different
manufacturers. A message is displayed
and the workstation continues to boot.
Note – If you only have one DIMM pair installed and those DIMMs have different
architectures, the OpenBoot PROM displays a message, and powers off.
Each CPU has four memory slots. The two blue slots make up physical bank 0 and
the two black slots make up physical bank 1 (FIGURE 3-4).
If a problem is found, OpenBoot PROM references memory by bank, for example:
NOTICE - CPU0 Bank 0 DIMMS are from different vendors.
The preceding message means that each of the two DIMMs in the bank 0 slots comes
from a different manufacturer. The workstation still attempts to use the DIMMs.
NOTICE - CPU0 Bank 1 DIMMs have different architectures and will
not be used.
This message means that each of the two DIMMs in the black slots has a different
internal memory layout. The workstation does not use the DIMMs.
The workstation must have at least one functional pair of DIMMs to display a
message. A workstation with more than one pair of DIMMs might display more than
one message.

3.2.4
Installing the DIMMs
Caution – If you are installing additional memory, remember that DIMMs must be
installed in matched pairs of DIMMs (FIGURE 3-4). The workstation requires a
minimum of one pair of matching DIMMs.
The minimum OpenBoot Prom level for the Sun Ultra 45 or Ultra 25 workstations is
OpenBoot 4.21.x. Before installing Sun Ultra 45 and Ultra 25 memory, verify that the
latest versions of OpenBoot PROM, system firmware, and recommended system
patches are installed on your system. If necessary, check the Sun System Handbook at
SunSolve Online:
http://sunsolve.sun.com/handbook_pub/
Note – If your Ultra 45 workstation has two CPUs and four DIMMs, the
workstation operates most efficiently with two DIMMs per CPU. DIMM connectors
are color-coded blue and black. You must install DIMMs in pairs in the same color
connectors.
Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in
antistatic bags before placing them on any surface.
Caution – Do not remove any DIMM from its antistatic package until you are ready
to install it.
1. Power off the system, attach an antistatic wrist strap, open and position the
chassis, and remove the access panel.
Refer to “Powering Off the Workstation” on page 2-4.
2. Remove the new DIMM from its antistatic container.
Caution – Handle DIMMs only by the edges. Do not touch DIMM components or
metal parts. Always wear an antistatic wrist strap when handling DIMMs.

3.5.4
Installation Considerations for Graphics
Accelerators
PCI-E 2 is the default console display. If there is no graphics accelerator installed
into PCI-E 2, consider the probe order shown in TABLE 3-3.
3.5.4.1
Default Console Display
During the boot sequence, device nodes are probed. The PCI slots are probed in the
order described in TABLE 3-3.
TABLE 3-3
PCI Card Probe Order
Probe
Order
Slot Identifier
Device Node
1
PCI4 (PCI-E 2)
/pci@1f,700000/ device 0
2
PCI2 (PCI-E 0)
/pci@1e,600000/pci@0/pci@3/ device 0
3
PCI3 (PCI-E 1)
/pci@1e,600000/pci@0/pci@8/ device 0
4
PCI1 (PCI-X 1)
/pci@1e,600000/pci@0/pci@9/pci@0,2/ device 1
5
PCI0 (PCI-X 0)
/pci@1e,600000/pci@0/pci@9/pci@0,2/ device 2
Unless you reconfigure the default, the first graphics accelerator occurring in the
probe order is designated the default console display and assigned the aliases
screen and /dev/fb.
3.5.4.2
Changing the Console Display
You can configure the OpenBoot PROM to designate a different graphics accelerator
as the console display. Use the show-displays utility, the nvalias command, and
the output-device parameter to make this change. For the following example, a
Sun XVR-2500 graphics accelerator is installed in physical slot PCI-E 2 as the default
console display and a Sun XVR-100 graphics accelerator is installed in slot PCI-X 0.
This example configures the Sun XVR-100 graphics accelerator to be the new console
display.
1. Obtain the ok prompt.
See “Obtaining the ok Prompt” on page 10-2.
3-16
Sun Ultra 45 and Ultra 25 Workstations Service and Diagnostics Manual • May 2006
2. Display the device nodes for the installed graphics accelerators.
For example:
ok
a)
b)
q)
show-displays
/pci@1f,700000/SUNW,XVR-2500@0
/pci@1e,600000/pci@0/pci@9/pci@0,2/SUNW,XVR-100@2
NO SELECTION
3. Select the graphics accelerator to be the new console display by typing its
respective letter.
For example:
Enter Selection, q to quit: b
The utility ends and the device node path is loaded into a text buffer.
4. Make an alias for the device node path.
For example:
ok nvalias newconsoledisplay (Ctrl + Y)
Type a space, hold down the Control key, and press the Y key.
5. Configure the output-device parameter for the new console display.
For example:
ok setenv output-device newconsoledisplay
6. Reset the OpenBoot PROM:
ok reset-all
The system now uses the Sun XVR-100 graphics accelerator as the new console
display.
Note – The default console display, the first graphics accelerator found in probe
order, is still aliased to screen. If you want to check the new console display, type:
test newconsoledisplay

In Solaris 10, the fault manager runs in the background. The fault manager performs
the following functions:
■
Receives telemetry information about problems detected by the system software.
■
Diagnoses the problems.
■
Initiates pro-active self-healing activities. For example, the fault manager can
disable faulty components.
TABLE 9-1 shows a typical message generated when a fault occurs on your system.
The message appears on your console and is recorded in the /var/adm/messages
file.
Note – The message in TABLE 9-1 indicates that the fault has already been diagnosed.
Any corrective action that the system can perform has already taken place. If your
workstation is still running, it continues to run.

NVRAM
The Sun Ultra 45 and Ultra 25 workstation motherboards use a nonvolatile random
access memory module (NVRAM) that stores parameters used for configuring
system startup (FIGURE 10-1). The NVRAM module uses a SEEPROM chip.
The workstation system configuration parameters are stored in NVRAM. These
NVRAM parameters contain values that determine the startup configuration of your
workstation. You can modify or reset the parameter values by using commands from
the ok prompt, or the eeprom command from a terminal window, or by using key
commands.

Obtaining the ok Prompt
When a Sun Ultra 45 or Ultra 25 workstation is put into run level state 0, the ok
prompt is displayed. At the ok prompt, you can make changes to the NVRAM and
conduct OpenBoot PROM tests (POST and OpenBoot Diagnostics). TABLE 10-1 lists
methods for obtaining the ok prompt, listed from most preferred to least desirable.
Caution – The Stop-A key sequence causes a system abort which loses the system
state and might corrupt file systems. Method 1 is the preferred procedure.

Changing NVRAM Configuration
Parameter Values
The NVRAM configuration parameter values set the startup behavior of the Sun
Ultra 45 or Ultra 25 workstation. Changes made to the variables typically survive
power cycling and if not configured properly, might have an adverse affect. Use
discretion when changing or resetting NVRAM configuration parameter values.

made with the setenv command are permanent, but require a reset or
power cycle to take affect.
set-default parameter
Resets the parameter to the default value.
set-defaults
Resets all parameters to their default values.
reset-all

Setting NVRAM Security Mode
You can restrict the set of operations that users can perform. When the securitymode parameter is set to either full or command, only users with the securitypassword may bypass the enforcement policy. TABLE 10-4 lists the different security
modes and their conditions.
TABLE 10-4

All commands except go require the security-password.
command
All commands except boot (without arguments) and go require the
security-password.
none
All commands are available, no password is required.
Caution – You must set the security password before setting the security mode.
Forgetting the password or configuring security mode before the password requires
a call to customer support to make the system bootable.
To configure security mode:
1. Obtain the ok prompt.
See “Obtaining the ok Prompt” on page 10-2.
2. Set the security password with one of the following methods:
Chapter 10
NVRAM
10-7
■
Type:
ok password
New password (8 characters max)
Retype new password:
ok
■
Or, type:
ok setenv security-password password
security-password =
ok
This is the only instance in which the security password is ever displayed.
3. Set the security mode to full or command:
ok setenv security-mode full
security-mode =
full
ok
4. Enable the security mode:
ok reset-all
Upon reset, the ok prompt appears as a > symbol and the password is required. For
example:
> printenv
Firmware Password:
After supplying the correct password, the command is run. If an incorrect password
is supplied, the user is required to wait for 10 seconds until authorization can be reattempted. For example:
> printenv
Firmware Password:
Sorry. Waiting 10 seconds.

eeprom Command
It is possible to display and change NVRAM configuration parameters from the
Solaris OS by using the eeprom command. The eeprom command is executed by
superuser in the form of:
# eeprom parameter=value
If no parameter is specified, the eeprom command displays only the current
NVRAM configuration parameter values, similar to the printenv command. For
example:
# eeprom
asr-policy=normal
test-args: data not available.
diag-passes=1.
.
.
.
diag-script=normal
diag-level=max
diag-switch?=false
To enable diagnostics, use the eeprom command in this example:
# eeprom diag-switch?=true
The eeprom command requires a system reboot for the changes to take effect. For
more information, refer to the eeprom man page.
10.5
Key Commands
This section describes how to use your USB keyboard to abort or reset NVRAM by
using the Stop-A or Stop-N equivalent commands:
■
■
“Stop-A Key Sequence” on page 10-10
“Stop-N Equivalent Key Sequence Procedure” on page 10-10
Chapter 10
NVRAM
10-9
Before powering on the workstation, ensure that the keyboard and mouse are
connected to the rear panel USB ports.
Note – The Stop-A and Stop-N key sequences are sometimes referred to as
“OpenBoot Emergency Procedures.”
10.5.1
Stop-A Key Sequence
Caution – Using the Stop-A key sequence while the Solaris OS is running causes a
system halt. The system state is lost, file systems are not synchronized, and data
might be lost or corrupted.
Use the Stop-A key sequence to abort an OpenBoot process. To issue the Stop-A key
sequence for the Sun Ultra 45 or Ultra 25 workstation, press both the Stop and A
keys (Stop-A) immediately after powering on the workstation. Hold both keys down
until the workstation beeps.
Note – Using Stop-A does not enable the workstation to perform a core dump. The
information from a core dump could be useful if the Solaris Operating System has
crashed.
10.5.2
Stop-N Equivalent Key Sequence Procedure
For older Sun systems, issuing the Stop-N key sequence upon startup resets
workstation configuration variables. The Sun Ultra 45 and Ultra 25 workstations use
a Sun Type-7 USB keyboard. It is not possible to issue a Stop-N key sequence with a
USB keyboard. By the time the USB keyboard driver is loaded, the interval to use the
Stop-N key sequence has expired. Instead, use the following procedure to reset your
workstation configuration variables. This procedure puts the Sun Ultra 45 or Ultra 25
workstation into a Safe NVRAM mode.
10.5.2.1
Resetting the NVRAM Temporarily
1. Power on the workstation and wait until the front panel Power button LED begins
to flash.
2. Quickly press the front panel Power button twice (similar to the way you would
double-click a mouse).
10-10
Sun Ultra 45 and Ultra 25 Workstations Service and Diagnostics Manual • May 2006
Note – Once the Power button LED stops flashing and stays lit, pressing the Power
button again powers off the system.
A screen similar to the following is displayed to indicate that you have successfully
reset NVRAM contents to the default values and the system is in Safe NVRAM
mode. If a screen similar to the following screen is not displayed, allow the system to
boot, shut down the system, and repeat Steps 1 and 2.

Safe NVRAM mode, the following nvram configuration variables have
been overridden:
’diag-switch?’ is true
’use-nvramrc?’ is false
’input-device’, ’output-device’ are defaulted
’ttya-mode’, ’ttyb-mode’ are defaulted
These changes are temporary and the original values will be
restored
after the next hardware or software reset.
ok
While the workstation is in the Safe NVRAM mode, some of the NVRAM
configuration parameters are reset to their default values. The reset parameters
include those parameters that are more likely to cause problems, such as TTYA
settings. However, these default NVRAM settings are reset only for one power cycle
and are not permanent. If you change configuration parameters while in Safe
NVRAM mode, those changes are permanent and do survive a reset.
TABLE 10-5 lists the configuration parameters that are reset to default values, and
describes those values.

Resetting the NVRAM Permanently
When the ok prompt is displayed, typing set-defaults discards any customized
NVRAM values and permanently restores the default values for all NVRAM
configuration parameters. See TABLE 10-3 for NVRAM configuration parameter
default values.
10.5.2.3
Workstation Power Cycling
Use one of the following two methods to perform a workstation power cycle by
shutting down and immediately restarting the workstation:
10-12
■
System reboot. A system reboot shuts down any running applications and the
operating system, then restarts the operating system. A system reboot does not
take to the workstation to a standby power state.
■
Shutdown and power on. Powering off the workstation shuts down any running
applications and the operating system, and takes the workstation to a standby
(power-off) state. To restart the workstation, you must manually press the Power
button, which initiates the boot process.

POST Overview
Power-on self-test (POST) performs tests on workstation core components such as
CPU and memory. POST checks low-level interaction between the CPU, caches,
memory, JBus, and the I/O bridge chip.
Typing the post command from the ok prompt initiates tests that check the CPU,
I/O bridge chip, and memory modules. The output of the post command is
directed to the serial port of the system under test. An external display device and a
Tip connection are required to view this output. Tip connections are described in
“Configuring an External Display Device” on page 11-17.
11.1.1
Configuring POST Output
The post command uses two variables to determine its output. The command
syntax is:
ok post level verbosity
11-1
where:
■
■
level is min or max
verbosity is min, normal, or max
TABLE 11-1 describes the diagnostic levels.

post Command
The post command enables you to override NVRAM settings and execute POST on
demand with different diagnostic levels and output verbosity. For example:
ok post level verbosity
where:
■
■
level is min or max
verbosity is min, normal, or max
If no diagnostic level or output verbosity is provided, the post command uses the
NVRAM settings for diag-level and verbosity. See “Changing NVRAM
Configuration Parameter Values” on page 10-3 for more information about these
parameters.

POST Output
The contents of the POST output depends on the values of the diagnostic level and
output verbosity. For the examples in this section, the Sun Ultra 45 or Ultra 25
workstation was configured with a single CPU and two 1-GByte DIMMs in slots 0 and
1.
Note – The 0> that precedes the output text is the CPU identifier and indicates that
the output is from POST. The 1> indicates CPU 1. If you do not see these characters,
the output is from the OpenBoot PROM.
11.3.1 post min normal
The following is the output of POST with min diagnostic level and normal output
verbosity. The duration of POST was 90 seconds. The left column of the table is the

Analyzing POST Messages
POST has three categories of messages:
■
■
■
11.4.1
“Error Messages” on page 11-14
“Warning Messages” on page 11-15
“Info Messages” on page 11-16
Error Messages
When an error occurs during POST, an error message is displayed. The error
message is bounded by the text ERROR and END_ERROR. Several error messages
might be displayed at different times during the POST process for any single error
condition.
The following error examples were caused by a defective 1-GByte DIMM in the slot
labeled DIMM0. The first error message occurred when the DIMMs were probed:
0>ERROR: TEST = Probe and Setup Memory
0>H/W under test = CPU0 Memory
0>Repair Instructions: Replace items in order listed by ’H/W under
test’ above
0>MSG = ERROR: miscompare on mem test!
Address: 00000000.00000000
Expected: a5a5a5a5.a5a5a5a5
Observed: a5a6a5a5.a5a5a5a5
0>END_ERROR
At address 00000000.00000000, there was a test pattern mismatch. A string of
a5a6a5a5 was observed when a string of a5a5a5a5 was expected.
The second error message identified where the fault was located:
0>ERROR: TEST = Probe and Setup Memory
0>H/W under test = CPU0: Bank 0 DIMM0, Motherboard
0>Repair Instructions: Replace items in order listed by ’H/W under
test’ above
0>MSG = Pin 72 failed on CPU0: Bank 0 DIMM0, Motherboard
0>END_ERROR
11-14
Sun Ultra 45 and Ultra 25 Workstations Service and Diagnostics Manual • May 2006
The DIMM in slot DIMM0 was at fault. Several other error messages were displayed,
and a summary was provided:
0>ERROR:
0>
POST top level status has the following failures:
0>
CPU0: Bank 0 DIMM0, Motherboard
0>
CPU0: Bank 1 DIMM0, Motherboard
0>END_ERROR
The DIMM in slot DIMM0 should be replaced. Because memory works in pairs,
POST disables both slots DIMM0 and DIMM1. POST returns system status and
control back to the OpenBoot PROM which then displays messages regarding the
results of POST.
For example:
Power On Selftest Failed.
CPU: 0 cause: CPU0: Bank 0 DIMM0, Motherboard
ERROR: CPU0 has 2048/4096MB of memory disabled
ERROR: POST failed
Because of the error, two DIMM slots have been disabled (bank0), so only half of the
original memory (2048/4096MBytes) is available for use.
Note – If only two DIMMs were installed and this set of errors occurred, the system
would have beeped three times and powered off.
11.4.2
Warning Messages
Warning messages have a structure similar to error messages, however the messages
are bounded by the text WARNING and END_WARNING. Warning messages do not
contain a Repair Instructions line.
Chapter 11
Power-On Self-Test
11-15
The following warning message example indicates that there is a DIMM size
mismatch in slots DIMM0 and DIMM1:
0>WARNING: TEST = Probe and Setup Memory
0>H/W under test = CPU0 Memory
0>MSG = DIMM size does not match for Dimm set 0, Dimm0=
00000000.40000000, Dimm1=00000000.20000000
0>END_WARNING
DIMM0 is a 1-GByte DIMM and DIMM1 is a 512-MByte DIMM.
11.4.3
Info Messages
Info messages are simple and are only preceded by the text, INFO. Info messages
provide noncritical facts, as seen in this example:
0>Probe
0>INFO:
0>INFO:
0>INFO:
0>INFO:

OpenBoot PROM Overview
OpenBoot PROM is the core software installed on the Sun Ultra 45 and Ultra 25
workstation motherboard. This software enables the Sun Ultra 45 and Ultra 25
workstation to load an operating system. The operating system can be loaded from
an installed hard drive, the DVD-dual drive, the network, or from some external
boot device. Because the OpenBoot PROM software resides within the NVRAM, it is
called firmware.
The OpenBoot PROM plays a major role in starting the Sun Ultra 45 or Ultra 25
workstation (For details see: “Power-On Sequence” on page 7-6.) If an error occurs
during that process, a message is usually displayed. You can use OpenBoot
Diagnostics tools to help diagnose system problems.
The OpenBoot PROM also has a collection of in-depth testing programs, available
from the obdiag prompt. These testing programs are described in “OpenBoot
Diagnostics” on page 12-6.

OpenBoot Diagnostics
The OpenBoot PROM software has a suite of tests that can help you diagnose
problems with the motherboard components and system interfaces to peripherals.
The OpenBoot Diagnostics tests are generalized and function at a low level. The tests
help you narrow down a problem to a specific component.
12.3.1
Starting OpenBoot Diagnostics
OpenBoot Diagnostics is started either from the console of the system under test or
remotely through an external display device. To run OpenBoot Diagnostics remotely,
see “Configuring an External Display Device” on page 11-17. An advantage of
running OpenBoot Diagnostics through a Tip connection is that long output can be
scrolled and saved.
1. Obtain the ok prompt.
See “Obtaining the ok Prompt” on page 10-2.
2. Set the auto-boot? property to false. Type:
ok setenv auto-boot? false
3. Reset the system. Type:
ok reset-all
The system restarts and the ok prompt is displayed again.
4. Set the diag-switch? property to true. Type:
ok setenv diag-switch? true
5. Start OpenBoot Diagnostics. Type:
ok obdiag

12.3.2
obdiag Menu
Once started, OpenBoot Diagnostics polls the system for device nodes. If the device
has a self-test, the device function can be verified. Some cards may not support selftest. When the poll is finished, OpenBoot Diagnostics lists a menu of the tests that
can be executed. For example:
_______________________________________________________________________
|

|
|
|
|

|
|
| diag-passes=1 diag-level=max test-args=
|
|_______________________________________________________________________|
The diagnostics displayed are dynamic. If a device node is not recognized, it is not
listed in the menu. For example, if the Sun XVR-100 graphics accelerator were
removed from the system, the Sun XVR-100 graphics accelerator test would not be
available, and all remaining tests would shift location and be renumbered. For
example:

The Sun validation test suite software, SunVTS, is a comprehensive software
diagnostic package that tests and validates hardware by verifying the connectivity
and functionality of most hardware components. SunVTS is a system exerciser that
you can use to check for intermittent or long-term failures.
SunVTS software executes multiple diagnostic tests from a GUI that provides test
configuration and status monitoring. The SunVTS interface can run on one
workstation to display a SunVTS test session of another workstation on the network.
13.2
Installing SunVTS
The SunVTS software is preinstalled on your Sun Ultra 45 or Ultra 25 workstation
hard drive. Use only SunVTS 6.1 or subsequent compatible versions.

A.1
Section A.1, “Power Management Overview” on page A-1
Section A.2, “Using Dtpower” on page A-2
Section A.3, “Modifying Power Management” on page A-3
Power Management Overview
To conserve power and to comply with the Energy Star program, mandated by US
Environmental Protection Agency, the Sun Ultra 45 or Ultra 25 workstation power
management features are enabled by default.
Note – The Sun Ultra 25 workstation meets or exceeds Energy Star guidelines in
operation only when using the Java™ Desktop System (Java DS) windowing system,
not while running the Common Desktop Environment (CDE) windowing system.
If you are currently using CDE, you can switch to the Java Desktop System by
logging out from a CDE session, then logging back in after selecting Java Desktop
System.
The Dtpower application reads and writes the Dtpower configuration to the
/etc/power.conf file. You can change power management settings in the Dtpower
application or you can make changes by editing the power.conf file. The Dtpower
application is easier to use. Editing the power.conf file allows more control over
power management than the Dtpower application provides.
This chapter provides some basic power management instructions. More detailed
information is in the following documentation:

CPU Description
The UltraSPARC IIIi processor is a high-performance, highly integrated superscalar
processor. It is capable of sustained execution of four instructions per cycle, even
with conditional branches and cache misses. Instructions are issued in program
order to multiple functional units, and executed in parallel. Instructions from two
basic blocks are issued in the same group to further increase the number of
instructions executed per cycle.
The UltraSPARC IIIi CPU supports full implementation of the 64-bit SPARC-V9
architecture, a 64-bit virtual address space, and a 43-bit physical address space. The
core instruction set includes graphics instructions that provide the most common
C-6
Sun Ultra 45 and Ultra 25 Workstations Service and Diagnostics Manual • May 2006
operations used for two-dimensional image processing, two and three-dimensional
graphics, image compression algorithms, and parallel operations on pixel data with
8- and 16-bit components.
C.2.3
Memory Controller
The memory system consists of the memory control unit (MCU) in the CPU, and two
physical banks (B0 and B1) of DDR-1 synchronous DRAM memory. Only registered
DIMMS are supported.
Clock buffering with a PLL is provided on the DIMMs. Each physical bank consists
of two 128-bit DDR-1 SDRAM DIMMs. These two DIMMs share an 8-byte data bus
and an ECC data bus. Both physical banks share an address/control bus. Since each
DIMM could be dual sided (upper and lower banks), there are maximum of four
data loads per physical bank. The cache line is split across the two physical banks.
Both banks are controlled by the memory controller.
Note – DIMMs must always be installed in pairs.
A memory controller sends requests in the pipeline, using 16 memory banks in the
Sun Ultra 45 when fully loaded, and 8 memory banks in the Sun Ultra 25 when fully
loaded.

Serial Ports
The Sun Ultra 45 or Ultra 25 workstation has two serial ports.
When powering off, the Sun Ultra 45 or Ultra 25 workstation sends a Break signal
out the serial ports. This break could interfere with a workstation-controlled server if
the server is operating through a Tip connection. Five solutions are available:
C.3.1
■
Configure for an alternate Break key sequence on the server.
■
Filter the Tip connection through a network terminal concentrator.
■
Disable the keyboard abort on the server.
■
Disable the Tip connection on the server.
■
Permanently Disable the Keyboard Abort or Configure an Alternate Break Key
Sequence on the Server
Configuring for an Alternate Break Key Sequence
on the Server
As superuser, open a terminal window and configure the alternate Break key
sequence. Type:
# kbd -a alternate
To invoke a keyboard abort, type Return, ~, Ctrl-B.
Note – You must reconfigure the alternate Break key sequence after a server power
cycle.
C.3.2
Filtering the Tip Connection Through a Network
Terminal Concentrator
The network terminal concentrator acts as a proxy between the Sun Ultra 45 or Ultra
25 workstation and the server under Tip control. The network terminal concentrator
communicates with the host Sun Ultra 45 or Ultra 25 workstation through the Telnet
C-8
Sun Ultra 45 and Ultra 25 Workstations Service and Diagnostics Manual • May 2006
protocol. If the workstation sends the BREAK signal, it is ignored by the network
terminal concentrator. Additionally, the concentrator does not send the BREAK signal
upon powering off.
C.3.3
Disabling the Keyboard Abort on the Server
This procedure configures the server to ignore the BREAK signal.
● As superuser, open a terminal window and disable the keyboard abort. Type:
# kbd -a disable
● To re-enable keyboard abort, type:
# kbd -a enable
Note – You must reconfigure the keyboard abort after a server power cycle.
C.3.4
Disabling the Tip Connection on the Server
● To disable the Tip connection, turn the server key switch to the lock position.
This action prevents any serial communication with the server. To re-establish serial
communications, turn the key to the unlock position.
